What is a key reason for the historical use of lead?

The historical use of lead primarily stems from its durability. Lead has been employed in a myriad of applications due to its ability to withstand corrosion and its robustness under various environmental conditions. This durability makes it an ideal material for pipes, roofing, and even as a component in paints and heavy-duty industrial applications.

The properties of lead allow it to maintain structural integrity over long periods, which made it a favored choice before the health hazards of lead exposure were fully understood. While other characteristics like weight and a low melting point contribute to its usage in certain contexts, the key appeal throughout history has been its durability, making it suitable for enduring use in construction and manufacturing.
